Architecture¶

• bench: trie benchmarking
• cmake: cmake files for build system, contains specification of inter-dependencies
• eth A command-line Ethereum full-node that can be controlled via RPC.
• ethkey: stand-alone key management
• ethminer: stand-alone ethash miner
• ethvm: stand-alone EVM execution utility
• evmjit: library for the EVM just-in-time compiler
• libdevcore: data structures, utilities, rlp, trie, memory db
• libdevcrypto: crypto primitives. Depends on libsecp256k1 and libcrypto++.
• libp2p: core peer to peer networking implementation (excluding specific sub-protocols)
• libethash: ethash mining POW algorithm implementation
• libethash-cl: ethash mining code for GPU mining (OpenCL)
• libethashseal: generic wrapper around the POW block seal engine. Also contains the genesis states for all ethash-based chains.
• libethcore: collection of core data structures and concepts
• libethereum: main consensus engine (minus EVM). Includes the State and BlockChain classes.
• libevm: Ethereum Virtual Machine implementation (interpreter).
• libevmasm: EVM assembly tools, also contains the optimizer.
• libevmcore: elementary data structures of the EVM, opcodes, gas costs, ...
• libweb3jsonrpc: json-rpc server-side endpoint, provides http and IPC (unix socket, windows pipe) connectors
• libwebthree: service connectors for ethereum, swarm/ipfs and whisper.
• libwhisper: whisper implementation
• rlp: stand-alone rlp en-/decoder
• testeth: tests for the modules formerly within the libethereum repo
• testweb3core: tests for the modules formerly within the libweb3core repo
• testweb3: tests for the modules formerly within the webthree repo
• utils/json_spirit: JSON parser written for Boost’s Spirit library.
• utils/libscrypt: scrypt implementation
• utils/secp256k1: implementation of the SECP 256k1 ECDSA signing algorithm.
